1. Sowing and raising seedlings can be raised in both spring and autumn. Spring sowing seedlings in small arch shed or sunny shed in late March or early April. The bed soil is combined with biological potassium and micro-fertilizer. After emergence, pay attention to the wind, spray 1 time "Baofeng micro-special". 20 days before planting, it was mainly controlled to make it a strong seedling.

Field management to strengthen water and fertilizer management after slow seedling, less watering in July, vigorous growth of spring onions in August, frequent watering, fertilizing and soil cultivation. "Baofeng Weishi" was sprayed for 5 times from the beginning of leaf growth. It can promote growth and increase production by 30%, 50%. It is wet but not dry from August to September, but it can not be flooded. Topdressing is needed for each watering, which is more than 20 centimeters away from the seedling. Harvest in mid-October.

4. "Botrytis cinerea" and "Fenmei Bike" were used to control friendly mildew and rust, "onion disease Ke" was used to control purple spot disease, "trichlorfon" was used to irrigate roots to control onion maggots, and "vegetable fly" or "Haoanwei" was used to control leafminer and onion thrips.
